Upon ment of parts to be hereinafter more fully the upper rear edge of this draft flue, the described, claimed, and illustrated in the damper or flue plate 21 is pivotally, mountaccompanying drawings, in which, ed, the pivot thereof having a crank arm 22 so ,lligui-e l. is a vertical scction of a locomoto which the operatingrod 23 is connected. tive boiler having our invention applied This rod may be held in adjusted position thereto; Fig. 2 is a top plan View; Fig. 3 is in a similar manner to the rod 15, as above a section taken. on the line 3 3.of Fig. 1; explained, and it will be understood that, and Fig. 4 is a section taken on the line upon the proper manipulation thereof, the 444i of Fig. 1. plate 21 may be raised to open the upper Ideferring in detail to the drawings, 5 end of the draft fine and permitthe entrance a id danger of air thereto. This plate, being inclined forwardly when in its openposition, acts to direct a strong current of air downwardly through the flue and into the smoke conducting pipes, whereby'the smoke is forcibly driven through said pipes into the rear ends thereof, and ventually into the fire boa: of the locomotive. In order to further facilitate this movement of the smoke, we provide the steam pipe 2% which is connected to the steam space of the extended through the rear wall of the draft flue. Interiorly of the draft line, said steam pipe is provided with the ln-anches 25 which project into the respective smoke conducting pipes 10 and have their extremities rearwardly turned or curved. A suitable valve 26 is located in the pipe 2% whereby the supply of steam to the pipes 1.0 may be controlled and regulated. By opening this valve, it will be understood that jets of steam under high pressure are delivered. into the respective pipes 10 so as to drive the smoke rearwardly through said pipes and into the fire box.

From the foregoing description, it is be lieved that the construction, manner of operation and several advantages of our in vention will be clearly and fully understood. The smoke and products of combustion entering the forward ends of the smoke pipes, is carried by the air draft and steam which is admitted to said pipes and forcibly delivered into the fire boX over the fuel bed, whereby it is consumed. It will be understood that the damper plate 12 is only disposed in its fully closed position when the fire box is fed with fresh fuel, and said plate is opened at intervals to permit the unconsluned products of combustion to pass off through the stack 9 to the atmosphere. By dampening the gas and smoke, its combus tion upon delivery to the fire box is assured. By the provision. of such a smoke consumer, the emission of smoke and sparks from the stack of the locomotive is greatly lessened of conflagrations, due to live cinders falling along the track,

Our invention iscomparatively simple in its construction, and may 'be readily applied "o loronur-tive boiler furnaces at present in common use. I

While we have shown and described the p'referrrai construction and arrangement of the several elements employed, it is to be locomotive boiler and is is overcome.

' I: understood that the apparatus is susceptible of considerable modification therein, and We, therefore, reserve the privilege of re sorting to all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus fully described our invention, what we desire to claim and secure by a damper plate mounted upon said flue. and means for positioning said damper plate to forcibly direct a draft of air downwardly through the flue and into said pipe.

2. The combination with a locomotive boiler furnace having a smoke coilecting chamber provided with a stack and a tire box, of spaced longitudinally extending pipes connected at one of their ends to said stack and having their other into the fire box, a damper plate mounted withinthe stack, means for 'iositioning said damper plate to direct the products of combustion into said pipes, an air flue communicating with said pipes intermediate of their ends, a plate pivotaliy mounted upon said flue, means for positioning said plate to forcibly direct an air draft downwardly through the due and into said pipes, a steam supply pipe conneied to the boiler and ex tending into said fine, and branch pipes extending from the steam supply pipe into the respective smoke conducting pipes and having their extremities extended longitudinally into said pipes.

In testimony whereof we hereunto aflix our signatures in the presence of two -witnesses.
